Prefabricated, stackable storage units deployed on job sites to house tools, equipment, or materials. Subcontractors use them to reduce mobilisation costs and adapt quickly to changing site layouts. Units can be reconfigured or relocated as project phases shift.
Modular Storage
Related Terms
Self-Build
IndustryA project where the owner acts as their own general contractor, hiring subcontractors directly rather than through a prime contractor. For field service companies, this often means faster access to work but requires closer coordination with the owner. Payment terms and scope changes are negotiated directly, so clear contracts are essential.
Rig Release
IndustryThe formal point when a drilling rig is demobilised and the operator ends the rig contract. For subcontractors, it signals the close of associated scopes of work and triggers final invoicing. Crew demob, equipment retrieval, and close-out documentation should begin immediately.
Spot Work
IndustryShort-term, unplanned jobs awarded without a long-term contract, typically filled on short notice. Subcontractors are engaged for a single scope or site visit at a negotiated day rate. Common in shutdown, turnaround, and emergency maintenance situations.
Legacy Site
IndustryAn older facility or work location operating on outdated infrastructure, systems, or equipment. Subcontractors often face non-standard conditions, ageing assets, and extra compliance requirements on these sites. Mobilisation and scoping costs can be higher due to undocumented or deteriorated site conditions.
Scope Validation
IndustryThe process of confirming that the work described in a contract matches actual field conditions before mobilising. Subcontractors use it to catch scope gaps that could lead to unpaid extras. Undocumented changes discovered on-site are easier to dispute without prior validation.
Helium Co-Production
IndustryThe extraction of helium as a byproduct alongside natural gas from the same well or facility. Subcontractors may encounter specialised separation equipment and handling protocols on co-production sites. Scope of work can expand to include cryogenic systems and helium storage, affecting crew certifications and equipment requirements.
